Yes, this is a bug, and having to reconvene the RDFS WG (since this is
not a mere editorial change) is an obstacle for pushing RDFS forward in
the W3C process.

I have a distinct recollection that you and I had lengthy discussions
about this last spring.

Anyway, I fear that this bug is related to a greater problem in RDFS
which begs to be addressed: properties of properties (such as range)
should be defined on a per-class basis - kinda tricky in our
property-centric approach.

As I said, we need to "rehydrate" the WG to do this.
